Environment
Retain 3.x
Situation
If I restore a deleted message back to my email system, will it show up as a different message in Retain after another archive dredge?
Resolution
Yes,
the restored message will show up in Retain again. This is because the
email system will see it as a new message and give it new header
information. So when you run another archive job Retain will see it as a
different message from the original.
However, there will still only be one copy of the message body and attachments because Retain uses single instance storage.
